Ein faserintegriertes Konzept zur Abstimmung der Emissionswellenlänge gepulster Faserlaser

In dieser Arbeit wird ein neues Abstimmprinzip für die Emissionswellenlänge gepulster Faserlaser vorgestellt, dass auf einem Faser-Bragg-Gitter (FBG) Array als spektraler Filter basiert. Die experimentelle...

An Electron Beam Profile Instrument Based on FBGs

Along with the dose rate and the total irradiation dose measurements, the knowledge of the beam localization and the beam profile/ energy distribution in the beam are parameters of interest for charged...

Simple structured illumination microscope setup with high acquisition speed by using a spatial light modulator

We describe a two-beam interference structured illumination fluorescence microscope. The novelty of the presented system lies in its simplicity. A programmable spatial light modulator (ferroelectric LCoS)...

Free charge carrier absorption in silicon at 800 nm

The transmission of a Ti:sapphire laser beam (c. w. and fs pulsed operation at 800 nm) through a 10 µm thin oxidized silicon membrane at 45° angle of incidence at first increases with the incident laser...

Modified bibenzimidazole ligands as spectator ligands in photoactive molecular functional Ru-polypyridine units? Implications from spectroscopy

The photophysical properties of Ruthenium-bipyridine complexes bearing a bibenzimidazole ligand were investigated. The nitrogens on the bibenzimidazole-ligand were protected, by adding either a phenylene...

High-Throughput Synthesis of Uniform Silver Seed Particles by a Continuous Microfluidic Synthesis Platform

Controlled silver particle geometries require at least a synthesis in two steps which strongly differ in their reaction kinetics. For the first step, the very fast seed formation, chaotic advection-based...

Simion Simon: An appreciation

Temperature–pressure induced nano-structural inhomogenities for vortex pinning in bulk MgB2 of different connectivity

Higher critical current densities, jc, (up to 1.6–0.15 MA/cm2 at 10–35 K) at low magnetic fields can be attained in MgB2-based materials, if a high manufacturing temperature (1050 _C) is used, while...

Visualized method of chemical enhancement mechanism on SERS and TERS

We review our developed visualization method of charge transfer (CT) for chemical enhancement mechanism on surfaceenhanced Raman scattering (SERS) and tip-enhanced Raman spectroscopy (TERS). Firstly, we...

Extinction properties of ultrapure water down to deep ultraviolet wavelengths

We report on the optical extinction properties of the clearest ultrapure water measured so far within the wavelength interval between 181 nm and 340 nm (TOC level: 2.6 ± 0.7 ppb, specific conductivity:...
